Write the area of an isosceles triangle having length of equal sides 'm' cm and third side 'n' cm,
1 Answer
Solution,
Here, length of each equal sides (a) = m cm,
length of third side (b) = n cm
Area of isosceles triangle (A) = ?
By using formula,
A = \(\frac b4\sqrt{4a^2-b^2}\)
= \(\frac n4\sqrt{4m^2-n^2}cm^2\)
